The following is a simple regression model created in Excel that attempts to estimate the capitalisation of a company (in millions) using a single independent variable (Current Price). (Please note: This sample exam question is just an indication of a Regression question. It would not be appropriate to use these two variables in a real life regression example.)

Explain how well the model predicts the variable "Capitalisation"? Predict the Capitalisation of a company that has a Current share Price of $2.20 using the regression equation mentioned in part(a).
